COLLIN COUNTY (CBSDFW.COM) – For the first time, the last known person seen with Christina Morris spoke exclusively with CBS 11 News about the events that happened before her disappearance.

Enrique Arochi graduated from Allen High School with Christina Morris. He says the two were acquaintances, and had mutual friends.

Arochi says he and Morris were part of a larger friends drinking and dining at the Shops at Legacy in Plano on Saturday, August 30.

Just before 4 a.m. Sunday, he and Morris walked together into the shopping center parking garage. The surveillance video captured by security cameras is the last known footage of Morris. The 24-year-old recounted the events after getting to the parking garage. “So we walked and we split and after I saw my car, I went to my car. I don’t know where she went, or if she went to her car. I just went to my car and left.”

Arochi says he does not remember their parting words, or if Morris ever made it to her car. “I honestly didn’t see anything. I was just walking to my car.”

“I just want them to come forward. It’s not only affecting her family, it’s affecting a lot of people around us. It’s just not fair if someone’s holding onto that piece of information that may lead to where Christina may be. I just want them to be honest and come forward.”
